What Is a Ductless Air Conditioner? Everything You Need to Know

Looking for the best ductless air conditioner for your home? Curious how ductless mini-split systems work and whether they’re worth it? You're in the right place. At Senville, we specialize in sleek, energy-efficient solutions designed to maximize home comfort—with modern performance you can count on.

What Is a Ductless Air Conditioner?

A ductless air conditioner—also known as a mini-split system—delivers heating and cooling to individual rooms or zones without the need for ductwork. These systems include two main components: an indoor unit mounted on a wall, and an outdoor condenser.

Unlike traditional central air, ductless ACs offer zoned comfort, allowing you to heat or cool only the spaces you use, when you use them.
